ive always been interested in calculations, so i want to try to calculate watt but I am stuck
bear in mind this is a pure hobby for me and i am far from a math genious
in this example i use a car
here is how far i have come
it accelerates from 22.2m/s to 33.3 m/s in 7 seconds
to calculate acceleration you do like this
highest speed-lowest/time 33.3-22.2=11.1 11.1/7 is almost 1.58
giving the car acceleration of 1.58m/s^2 so far so good
-----------------------------------------------------------
next is calculating work
work= mass*acceleration^2
so if the car is 1200kg(Newton)
then we take 1200* (1.58*1.58) = 2996 joules (this is correct i hope)
--------------------------------------------------------------------------
and this is where i get stuck because the formulas i find state that watt=work/time
2996joules/7sec is obviously wrong...
can anybody help me?
